So I go to check out my EGR system and find two lines disconnected from it that I'm 90% sure weren't disconnected before I took it for emissions.
Maybe the tester/mechanic pulled 'em to get me to pay to fix it? Who knows.
Anyway -- How badly would having two of the lines pulled affect NO?
Disonnected Lines:
Red dots show pulled lines.
